What should I do if there is abnormal sound of side brush while Deebot is working?

Updated on 2021/03/05
1. When the side brush works for a long time, it will bend to the body of Deebot due to debris or floor, causing friction with the Deebot body.
2. It is recommended to remove the side brush, smooth the bristles, and bend the bristles inward to make the side brush better close to the floor.
